REVERSIBLE FEEDER FOR INGOT HOLDS.

Application filed February 12, 1923. Serial No. 618,545.

To all whom it may cmwem:

Be it known that we, .Bnoomrmm) H. Howmm and ERNEST J. TURNER, citizensof the United States, residing, respectively, at

5. city of Washington, District of Columbia,

and Pittsburgh, county of Allegheny and State of Pennsylvania,-haveinvented certain new and useful Improvements in Reversible Feeders forIngot Molds, of which the following is a specification.

Our invention relates to improvements in reversible feeders for ingotmolds.

The object of our invention is to provide a reversible feeder for ingotmolds whereby the distance the feeder extends intothe mold may bereadily varied, and whereby the length of the ingot can be made greateror less in the same mold, and at the same time produce a feeder' havingall of the advantages of the ordinary feeder, to prevent seams and holesknown as piping and also reduce segregation to a minimum.

Another object of our invention is to rovide a feeder of this characterin which the same means supports the feeder in its normal and reversedposition and said meansfirmly supporting the feederwithin the upper endof thecmold agamst longitudinal or lateral movement.

Another objectof our invention is to provide a feeder of this characterwhich will v have a great number of. adjustments for varying the lengthof the ingot in the mold, and at the same time provide a simple, cheapand effective reversible feeder having certain details of structure andcombination of parts hereinafter more. fully set forth.

In the accompanying drawings:

Fig. 1 is a perspective view of an ingot mold showing our improvedfeeder applied thereto. Fig. 2 is avertical sectional view of Fig. 1showing the feeder in the reversed position in dotted lines.

Fig. 3 is a side elevation of our improved feeder.

a form of feeder.

Fig. 7 is a side elevation partly in section of another modified form offeeder.

Fig. 8 is a top plan view of another modified form of feeder.

Fig. 9 is a top plan view'of a still further modified form of feeder.

Fig. 10 is a vertical sectional view of a mold and feeder showinganother modified form of feeder.

Fig. 11 is a sectional view of a mold showing in side elevation anotherform of feeder for having a greaternumber of adjustments Fig. 15 is aside elevation similar to Fig.

14 showing the ribs having a single slit.

Referring now to the drawings, the numeral 1 represents the ordinaryingot mold, and 2 our improved feeder in the form shown in Figures 1, 2and 3. The feeder '2 is provided on each side with two short ribs 3 and4, which have their upper ends 5 closer to the upper edge 6 of thefeeder than their lower edge 7 are to the lower edge 8 of the feeder. Bythis structure it will be seen that by reversing or inverting the feederas shown in dotted lines Fig. 2, the feeder will not extend so far intothe mold and a longer ingot will be produced. 1

In Fig. 4, the feeder 9 is of a circular form and is provided with awedge-shaped rib extending outwardly entirely around the same, and saidrib being closer to the upper Y In Fig. 6 we have shown two oppositesides of the feeder 15 provided with longitudinally arranged flanges 16and 17 placed nearer one end of the feeder than the other.

Fig. 7 shows the circular feeder 18 having a continuous rib 19 aroundthe same, and rectangular in cross section and arranged nearer one endof the feeder than the other.

Fig. 8 shows the feeder 20 having all, four sides provided with flanges21, 22, 23 and 24, which are of a length less than the width of the sidehaving the corners free from engagement with the upper edge of the moldwhen the feeder is inserted in the mold.

In Fig. 9, we have shown the feeder with two opposite sides having theflanges 26 and 27 of a length less than the width of the sides of thefeeder.

In Fig. 10, we have shown the feeder 28 having two sets of lugs 29 and30 carried by the outer periphery and said lugs weakened as indicated at32 and 33, whereby either set of lugs may be broken for giving four adjustments in the mold. By reversing or inverting the feeder less of thefeeder will extend into the mold. By breaking of thelugs 29 andinverting the mold, a considerable more of the feeder will enter themold, and by breaking off the lugs 30 nearly the whole feeder will enterthe mold.

In the form shown in Fig. 11,-We have shown the feeder 34 with fivehorizontally arranged staggered rows of lugs 35, 36, 37, 38 and 39,whereby a great number of adjustments of the feeder in the mold isobtained.

In Fig. 12, in order to give further adjustments of the feeder thanshown in the other figures, a fire brick or block 40 of non-combustiblematerial may be placed on the upper edge of the mold below the ribs 3and 4.

In Fig. 13, we have shown a.modified form of supporting ribs. In thisform the ribs 41 are made comparatively thin, and of considerable lengthto give sutficient strength to sustain the weight, but being thin can bereadily broken off so the feeder may enter the mold different distances.

In Fig. 14, we have shown the projections 42 of an elongated narrow formhaving their ends different distances from the ends of the feeder andhaving cross cuts 43 so that any portion of the lug or projection 42 maybe broken to vary the distance feeder enters the mold.

In Fig. 15, the same principle is employed as in Fig. 14, except theribs 44 are provided with a single cross cut 45.

We claim:

1. A feeder for ingot molds comprising a reversible body portion, and anintegral projection carried by 'the body portion and adapted to supportthe feeder with either end in the mold.

2. A feeder for ingot molds comprising a reversible body portion, and anintegral projection carried by the body portion nearer one end than theother and adapted to support the feeder with either end in the mold. 3.A feeder for ingot molds comprising a reversible body portion, anintegral projection carried by the outer face of the body portion nearerone end than the other and adapted to support the feeder with either endin the mold and whereby a block may be placed on the upper end of themold below the projection for raising the feeder in the mold.

4. A feeder for ingot molds, comprising a body portion, and projectionscarried by the outer face of the body portion and forming means forsupporting the feeder within the mold and said projections weakened sothat they may be broken off to allow the feeder to enter the molddifferent distances.
